APPEARANCE: A koto is long and harp-like, and the national instrument of Japan.

BEHAVIOR: A koto which was once played frequently but later forgotten about and stored away can transform into the koto furunushi. These koto look like wild beasts, and remember every song that was ever played on them. They play them when nobody is around to see, and causing everyone to wonder where the music is coming from. Koto furunushi prefer to play old, forgotten tunes which have fallen out of style and have long vanished from people’s memory.
